Pretty good for wax
Work well with rigs and with peak pro. Some of them cracked, but that was likely user error on my end. Considering I lose these in the carpet frequently good value for the price

Great for pivots
Use these for my puffco pivot. Makes a wonderful difference and a reasonable price for how long they last me

Works well with Carta V
They spin in my Carta V and keep the wax moving. These work well!

Overall decent
Using them as terp pearls they got black pretty quick with regular iso baths. They work well and spin fast even with quite a few in my banger. They’re cheap. Get some

Good price for the convenience - Wrong size, ordered twice to be sure.
These are 3mm, perfect for e-rig users. (I use a 6mm + 3mm)They do not play too nicely with iso, and crack easily if heat shocked or mishandled.Careful not to use too much force q-tipping or else you may catapult them out of the atomizer.
